An Assessment of Heavy Metal Concentrations in Adirondack Waterfowl

Thu, 04/28/2016 - 22:53
Abstract: We analyzed heavy metal concentrations in waterfowl liver and breast tissue from ducks harvested within the Adirondack Park from October 3 to November 13, 2015. Interspecific, intersex, and feeding behavior variation in heavy metal concentrations were assessed. Waterfowl from two feeding behavior groups (diving and dabbling) were harvested from the watershed within a 50 mile radius of Paul Smith’s, New York. Harvested waterfowl species included mallard (Anas platyrhynchos), American black duck (Anas rubripes), common merganser (Mergus merganser), ring-necked duck (Aythya collaris), bufflehead (Bucephala albeola), and hooded merganser (Lophodytes cucullatus). Legal harvest of these species during regulated New York State duck hunting season allows for permissible use of internal organs for heavy metal determination. Dry weight (mg/kg) of digested liver and breast tissue samples were analyzed using atomic absorption spectroscopy. Due to unknown laboratory error, absolute concentration values were inaccurate, thus, rendering accurate analyses unfeasible. However, relative observable trends were able to be assessed given our data’s high precision. Analyte concentrations were significantly greater in liver tissues and there were significant differences between species. Variation in mercury, lead, bismuth, cadmium, chromium, and zinc concentrations in waterfowl serve as an indicator of the presence, cycling, bioaccumulation, and temporal trends of these metals in northeastern aquatic habitats.

Rooted Education: learning from aquaponics

Sat, 04/30/2016 - 15:02
Abstract: Aquaponics is the integration of soil-less agriculture (hydroponics) within closed-loop aquaculture systems to reduce the toxic accumulation of nutrient waste from aquatic animals. Bacteria naturally establish to purify water by oxidizing the ammonia secreted by fish, which reduces the toxicity of effluent while creating a usable nitrogen source for plants. The conversion of ammonia and nitrite into nitrate by living bacteria communities is called a biological filter, or biofiltration (FAO 2014). Aquaponics would not be possible without biofiltration; the slightest amount of ammonia would be fatally toxic to fish, and plants wouldn't receive the nitrates they need to grow. There are unique opportunities offered by an aquaponics system to learn about ecological and human communities. 1.1. Aquaponics enables users to grow fish and agricultural plants with limited space and resource use (water, soil, and time). This enables an aquaponics user to invest less physical energy and time into expanding sustainable food resources for their household use. 1.2. A small aquaponics system could promote cultural values of self-sufficiency, energy consciousness, and connection to food systems. It could inspire individual efforts to produce food for one’s household, to build healthier and more resilient systems, and a greater appreciation for farming. Therefore, this project aims to actualize a mobile and functional aquaponics system for the educational benefit of the Paul Smith's College community. I will provide the background knowledge needed to maintain an aquaponics system, as well as describe the general concept of aquaponics design.

Food Allergies, Dietary Restrictions, and the Foodservice Industry

Thu, 12/03/2015 - 22:59
Abstract: For modern culinary professionals, food allergies and restricted diets present one of the biggest challenges in daily work. Ranging from an anaphylaxis-triggering peanut allergy to a preference for avoiding meat on Fridays, dietary restrictions and food sensitivities cover a wide variety of potential hurdles, and potentially inspirational guidelines, which foodservice professionals must navigate in order to be successful. On one side, a rise in the number of those with allergies or dietary restrictions presents an added challenge, but on the other, it presents an opportunity. Diners with such restrictions are becoming more and more comfortable with going out to dinner; that there will be some accommodation is now expected by consumers, rather than hoped for. The definition of “food allergy,” according to the Mayo Clinic, is “an immune system reaction that occurs soon after eating a certain food.” However, according to many experienced foodservice workers, the definition is “an annoying request from a customer who’s probably lying, anyway.” Of the many challenges contemporary chefs, culinarians, and food service professionals face, food preparation and service for those with allergies and restricted diets is one of the most prevalent, as well as one of the most misunderstood. Foodservice professionals will tell you that some of the most [annoying, silly, overblown, difficult, frightening] requests they receive while working are for special adjustments to accommodate a food allergy. When a chef is asked if the signature pasta dish can be made without gluten, his reaction is too often a mix of ire, disgust, and even embarrassment. Should a patron make a simple request that his or her food be prepared away from peanuts, images of anaphylactic shock and ambulances in the parking lot dance demonically through the front-of-house manager’s head. Such requests, however, seem to be popping up more and more often in our world. According to the CDC, “The prevalence of food allergies among children increased 18% during 1997-2007.” About 15 million Americans suffer from food allergies, as well as about 18 million Europeans. With such a rapid increase in those numbers, one would think the opportunity to impress customers with special diets might make a chef happy, rather than feeling as though he has been offended. The patience of chefs grows thinner still, however, when such requests are not a matter of health, but a matter of preference. For those who, for various reasons, adhere to a vegetarian or plant-based diet, or who follow certain religious dietary restrictions such as Islamic Halaal, finding a restaurant where the staff is ready and willing to accommodate can sometimes be difficult. For contemporary food handlers, ethics and morality play a massive role in serving such customers. A vegetarian diner, for example, may not know that the house minestrone soup is made with chicken stock in place of vegetable stock. Even after eating the soup, that customer will likely never know. In such situations, the decision to serve certain foods comes down to how much respect for his or her customers a chef has. It is my belief that the largest contributing factor towards the negative feelings chefs harbor over dietary restrictions is a lack of education and experience in handling such requests. Things unknown have always been a source of anxiety for a majority of human kind. That anxiety is why we are explorers and innovators; we subconsciously want to make things known. In order for foodservice professionals to handle the large number of diners who now request special items, it is necessary that they be educated from the earliest stages of their careers to expect, to accept, to interpret, and to enjoy working with those types of challenges. By doing so, the food and beverage industry will be a much more friendly world for all consumers, and a much more profitable one for all industry professionals.

Cheese

Tue, 05/05/2015 - 17:05
Abstract: This culminating experience happens in two phases. Throughout the semester, students have been taking on the role of Executive Chef in our Palm Restaurant. They have each created a menu, ordered food supplies, developed budgetary proposal, and assigned duties pertaining to food production and front of house service. Each dinner took on a different food related theme that the students researched and developed. This poster session provides the students to describe their process, their findings, and what they learned from the experience. My theme was based on cheese.

Analysis of common water sampling techniques used to assess lake trophic state

Sat, 12/05/2015 - 00:21
Abstract: Volunteer lake management programs (VLMPs) across the country employ different surface water sampling techniques to establish long-term trends in nutrient availability and trophic state. The three most common techniques are a surface grab (SG), 2m integrated tube sampler (IT), and a discrete sampler, such as a Van Dorn or Kemmerer bottle deployed to a depth of 1.5m (DD). These various sampling techniques vary not only in depth, but also in cost and ease of use. The objectives of my study are to 1) determine if there is a statistical difference in chlorophyll-a (chl-a) and total phosphorus (TP) concentration obtained between the three different sampling techniques, 2) determine if the treatment effect (sampling device) varies over time, 3) determine which method has the least amount of variability, and 4) determine if sampling technique ultimately influences trophic state classification. The study was conducted on Upper St. Regis Lake, Paul Smiths, New York. I collected 10 samples from the lake using the three different techniques during the months of June – August, 2015. I found a significant difference in chlorophyll-a concentration between sampling techniques during June and July, and during the month of July for TP. The three sampling techniques yielded similar variability for chlorophyll-a but significantly different variability for TP. Ultimately, the trophic status rating for Upper St. Regis was not effected by sampling technique. My study suggests that VLMP should utilize a SG or IT rather than a costly DD sampler.

Interpreter's Guide to the Finger Lakes Trail

Wed, 04/29/2015 - 21:44
Abstract: Guidebooks help hikers to navigate trail systems and gain a better understanding of their surroundings. Many types of guides exist for popular long distance hiking trails such as the Appalachian Trail, the Pacific Crest Trail, and the Continental Divide Trail. The Finger Lakes Trail (FLT) runs 558 miles across the base of New York State, yet has very little associated literature. I hiked a 52 mile section of the Finger Lakes Trail from Ellicottville to Portageville in western New York. Using observations from the trail and related literature, I wrote an interpretive guide for this section. My FLT interpretive guide covers topics related to planning and packing for a multiday backpacking trip, natural history of western New York forests, the story of the development of the FLT system, and backpacking ethics. This work will help satisfy the human need to acquire knowledge and potentially enrich the experience of FLT hikers.

Limnological Report of Marvin (Potters) Pond

Thu, 04/30/2015 - 09:51
Abstract: Long term data of limnological conditions is crucial to understand lentic freshwater ecosystems. Marvin (Potters) pond is a 2.04 hectare kettle pond located in Franklin County, New York in the Northern Adirondack Park. There have been numerous short studies of the pond over the past 30 years but the pond has never been intently monitored to date. The pond is assumed to be meromictic by the NYSDEC. The objectives of this study are to 1) calculate the morphometry of the pond and its watershed; 2) the determination of the trophic status of the pond; 3) to document the chemical composition of the pond, particularly as it relates to acidity and acid neutralizing capacity; 4) to document the annual dynamics of temperature and dissolved oxygen. Evidence from profile data on dissolved oxygen and total iron suggests that the pond is monomictic with the capability to be meromictic under certain climatic conditions. The mixing period of the pond occurred in the month of November. The morphometry of Marvin pond was found to have a conical cross sectional area and large depth for the surface area of the pond. The trophic state of Marvin pond was found to be eutrophic for chlorophyll-a and total phosphorus concentrations but mesotrophic for the secchi disk reading. The acidity of the pond was found to be high with a low buffering capacity.
